A bit hard to tell what you are actually doing, so this is merely a guess: You are burning a data CD with files (WAV, WMA and now suggested, FLAC). Right?An audio CD is something different. It is not such a kind of file, in fact not even such a kind of file system. The Onkyo wants an audio CD, not a data CD with audio in the data. Big difference.

Some players can read data CDs though (maybe all BluRay players can, I don't know) and they may or may not be equipped with the codec in question.

Assuming you really do want to burn a data disc and your CD player is capable of playing it, the most commonly supported codec will be MP3 or AAC. Copy your MP3 files to CD-R just as they are and convert everything else to MP3 V2 and you'll be good to go. Organize it all in folders by [ARTIST\ALBUM\TWO-DIGIT_TRACK - TITLE.mp3] and it will be easy to navigate.

If your CD player is not capable of playing data discs, use Burrn to easily create standard audio CD-Rs from practically any music file format.

Hi i mean strictly AUDIO albums.

I burned zeppelins Hoth to WAV from cd burnerxp; it plays on my blu ray but the Onkyo cd player wont play it at all.

You may call them AUDIO all you like, but if, as you say, you are burning wav files to a cd, they are data cd's not audio. As already explained it is not uncommon that one of your hardware players is choking on them. Burn them as audio and they will play.

There is a huge amount of information on this available via search and likely within the wiki.

When you put the CD in a computer and list the directory (like, in Windows, dir D: or whatever the drive letter is -- open a command window first with Winkey-R cmd Enter), does it show filenames or does it show Track01.cda?

If the latter ... is your CD player ... how much would it have to be, ten to fifteen years or older? Since CD-R is a newer medium than CD, then back in the stone age, there were quite a few CD players that couldn't digest the moonshine.

I burnt them as AUDIO discs via cd burnerxp

If you put one of these disks into your computer, what type of file do you see on it?

Did you catch the fact that most older CD players will not play CD-R disks, regardless of the format of the material written to them? They will only play pressed audio CD disks.

How old is old? I don't recall when CD-R for home use became common, perhaps sometimes in the 90s. Before that, audio CD players were not made to be able to play CD-R; home made CD-R audio CDs just didn't exist, the specifications to manufacturer CD players that handle them did not exist. Any blu ray player is a different story. The CD-R specs were already ancient history before the first such player was conceived.

My money is on CD-R incompatibility, as was suggested. Especially if the CD player is older.Could be also that it's not CD-R incompatibility in general, but an issue of burning speed or something. So perhaps try with a lower speed or a different brand of CD-Rs.. maybe even with different burning software (although I've never had problems with CDburnerXP).

I didn't miss that, its just not true in my experience. I used to burn lots of disks back in the 90s when CDRs were rare. I paid quite a lot of money for a 2X burner when they were new. Even then, it was relatively rare to find a device that wouldn't read a disk. 15 years later I consider it downright unlikely.

As I said before, I'm guessing its not a real audio CD, and as before I recommend verifying that
